I am running Ubuntu MATE 19.04 on a Lenovo Thinkpad T470, without any dedicated graphics of any kind. I have the same issue. Upon closing the laptop, the screen turns off, but the machine is not suspended. When I re-open the screen it is black, but still on. Moving the mouse, using the keyboard doesn't do anything to fix the problem. Changing the virtual terminal Ctrl + Alt + F1, then back again Ctrl + Alt + F7 starts the screen again, the lock screen is displayed.
